The Web Services Security component in IBM WebSphere Application Server (WAS) 6.0.2 before 6.0.2.31 and 6.1 before 6.1.0.19, when Certificate Store Collections is configured to use Certificate Revocation Lists (CRL), does not call the setRevocationEnabled method on the PKIXBuilderParameters object, which prevents the "Java security method" from checking the revocation status of X.509 certificates and allows remote attackers to bypass intended access restrictions via a SOAP message with a revoked certificate.

The HTTP_Request_Parser method in the HTTP Transport component in IBM WebSphere Application Server (WAS) 6.0.2 before 6.0.2.31 allows remote attackers to cause a denial of service (controller 0C4 abend and application hang) via a long HTTP Host header, related to "storage overlay" on the stack and a "parse failure."

Unspecified vulnerability in the serveServletsByClassnameEnabled feature in IBM WebSphere Application Server (WAS) 6.0 through 6.0.2.25, 6.1 through 6.1.0.14, and 5.1.1.x before 5.1.1.18 has unknown impact and attack vectors.

Unspecified vulnerability in the Administrative Scripting Tools (such as wsadmin or ANT) in IBM WebSphere Application Server 5.x and 6.0.x has unknown impact and attack vectors.

The web container in IBM WebSphere Application Server (WAS) before 6.0.2.21, and 6.1.x before 6.1.0.9, sends response data intended for a different request in certain circumstances after a closed connection error, which might allow remote attackers to obtain sensitive information.

IBM WebSphere Application Server before 6.1.0.1 allows attackers to obtain sensitive information via unspecified vectors related to (1) the log file, (2) "script generated syntax on wsadmin command line," and (3) traces.

Multiple unspecified vulnerabilities in IBM WebSphere Application Server before 6.1.0.1 have unspecified impact and attack vectors involving (1) "SOAP requests and responses", (2) mbean, (3) ThreadIdentitySupport, and possibly others.

Cross-site scripting (XSS) vulnerability in the 500 Internal Server Error page on the SOAP port (8880/tcp) in IBM WebSphere Application Server 5.0.2 and earlier, 5.1.x before 5.1.1.12, and 6.0.2 up to 6.0.2.7, allows remote attackers to inject arbitrary web script or HTML via the URI, which is contained in a FAULTACTOR element on this page. NOTE: some sources have reported the element as "faultfactor," but this is likely erroneous.

IBM WebSphere Application Server 5.0.2 and earlier, 5.1.1 and earlier, and 6.0.2 up to 6.0.2.7 records user credentials in plaintext in addNode.log, which allows attackers to gain privileges.
